CROSS REFERENCE TO PRIOR APPLICATION

This application is a continuation of U.S. patent application Ser. No. 12/713,990 (filed on Feb. 26, 2010), which claims priority to Japanese Patent Application No. 2009-055565 (filed on Mar. 9, 2009), which are all hereby incorporated by reference in their entirety.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to an information processing apparatus, an information processing method, and a program.

Description of the Related Art

There is disclosed a technology which enables to input coordinates of one continuous line in the case where a plurality of coordinate input parts are used as one integrated coordinate input part and if a pen is moved from one point on an individual coordinate input part to another individual coordinate input part (for example, see Japanese Patent Application Laid-Open No. 9-311757). According to the technology, in the case where a plurality of screens for inputting coordinates are present, it is possible to input coordinates of one continuous line, but it may be impossible to move an object or the like displayed on the screen from one screen to another screen.

Further, in recent years, there have appeared devices such as mobile phones and game machines each having two screens. However, most of those devices often have one of the screens formed of a touch panel and the other screen formed of a screen only having a display function. It is difficult to communicate between the two screens, and, because of the fact that only one of the screens is the touch panel, there are many cases where the fact confuses the users.

Most of the devices having two screens are each in a foldable form, and there is a hinge between those two screens. Accordingly, in between the screens of the device which includes two screens each formed of a touch panel, there exists a region where a sensor does not exist or a physical barrier.

SUMMARY OF THE INVENTION

However, in the state where the region where a sensor does not exist or the physical barrier exists as described above, it has been difficult to drag and drop an object from one screen to the other screen. Then, both screens are each designed as isolated space, and it has been difficult to effectively utilize both screens to an extent that corresponds to a screen area obtained by adding the areas of both screens.

The present invention has been made in view of the above issues and it is desirable to provide a novel and improved technology capable of, in an information processing apparatus having two screens each formed of a touch panel, easily performing an interaction between the two screens.

According to an embodiment of the present invention, there is provided an information processing apparatus including a first touch panel having a first contact surface which can come into contact with an operating body and capable of acquiring first contact coordinate information indicating a contact position on the first contact surface with the operating body and also having a first display surface and capable of displaying information in the first display surface, a second touch panel having a second contact surface which can come into contact with the operating body and capable of acquiring second contact coordinate information indicating a contact position on the second contact surface with the operating body and also having a second display surface and capable of displaying information in the second display surface, a storage section which stores object data specifying an object and object coordinate information indicating a position of the object on the first display surface, and a control section which causes the object specified by the object data, which is stored in the storage section, to be displayed as a first object at a position indicated by the object coordinate information, when the first touch panel acquires the first contact coordinate information, determines whether the first object is selected by the operating body based on the first contact coordinate information and the object coordinate information, if it is determined that the first object is selected by the operating body, causes a second object, which is obtained by duplicating a part or all of the first object, to be displayed at a predetermined position on the second display surface, when the second touch panel acquires the second contact coordinate information, determines whether the second object is selected by the operating body based on the second contact coordinate information and in-second display surface destination coordinate information which indicates the predetermined position, and if it is determined that the second object is selected by the operating body, hides the first object displayed at the position indicated by the object coordinate information and also updates the object coordinate information with the in-second display surface destination coordinate information.

The control section may acquire movement information indicating a direction and a distance in which the operating body moves on the first contact surface while being in contact therewith, may decide in-first display surface destination coordinate information, which is a destination of the first object within the first display surface, based on the movement information, may update the object coordinate information with the in-first display surface destination coordinate information and may also move the first object to a position indicated by the object coordinate information after being updated, may determine, based on the object coordinate information after being updated and coordinate information within a predetermined region on the first display surface, whether the first object has entered the predetermined region, and, if it is determined that the first object has entered the predetermined region, may determine that the first object is selected by the operating body and may cause the second object to be displayed at the predetermined position.

The storage section may store coordinate information of a predetermined point which forms the object and the control section may determine whether the coordinate information of the predetermined point corresponds to one of a plurality of pieces of coordinate information within the predetermined region, and, if the coordinate information of the predetermined point corresponds thereto, may determine that the first object has entered the predetermined region.

<1. First Embodiment>

First, the first embodiment of the present invention will be described.

[1-1. Schematic Configuration Example of Information Processing Apparatus]

FIG. 1 is a diagram showing a schematic configuration example of an information processing apparatus according to the first embodiment of the present invention. In the first embodiment of the present invention, a description will be made on an information processing apparatus 100 (100 a) including two touch panels 101 (a first touch panel 101 a and a second touch panel 101 b). The first touch panel 101 a has a first display surface 102 a, and the second touch panel 101 b has a second display surface 102 b. An object 103 is displayed in at least one of the two display surfaces 102. In the example shown in FIG. 1, the objects 103 (103 a, 103 b, and 103 c) are displayed in the first display surface 102 a, but the number of the object 103 is not particularly limited and may be any as long as it is 1 or more. Further, the kind of the two touch panels 101 (first touch panel 101 a and second touch panel 101 b) is not particularly limited.

Hereinafter, the case where the object 103 b is moved from the first display surface 102 a to the second display surface 102 b will be described, and when the object 103, which is to be moved, is the object 103 a, the object 103 c, another object, or the like, the object 103 can be moved similarly. Further, it is also possible to move the objects 103 (103 a, 103 b, and 103 c) and another object from the second display surface 102 b to the first display surface 102 a in the same manner as in the case where the object 103 b is moved from the first display surface 102 a to the second display surface 102 b.

[1-2. Hardware Configuration of Information Processing Apparatus]

FIG. 2 is a block diagram showing a hardware configuration of the information processing apparatus according to the first embodiment of the present invention. As shown in FIG. 2, the information processing apparatus 100 a according to the first embodiment of the present invention includes the first touch panel 101 a, the second touch panel 101 b, a non-volatile memory 106, an RAM (Random Access Memory) 107, and a CPU (Central Processing Unit) 108.

The non-volatile memory 106 is a device for storing data, and includes, for example, a magnetic storage device such as an HDD (Hard Disk Drive), a semiconductor storage device, an optical storage device, or a magneto-optical storage device. The non-volatile memory 106 stores programs executed by the CPU 108 and various kinds of data.

The RAM 107 temporarily stores programs used by the CPU 108 and parameters which appropriately change during execution thereof.

The CPU 108 functions as an arithmetic processing unit and a control unit and controls the overall operation inside the information processing apparatus 100 a or a portion thereof according to various programs recorded in the non-volatile memory 106 or the RAM 107.

In the foregoing, an example of the hardware configuration which can realize the function of the information processing apparatus 100 a according to the first embodiment of the present invention has been shown. Each of the above components may be configured using general-purpose members or hardware specialized for the function of each component. Therefore, the hardware configuration to be used can be changed appropriately in accordance with the technical level each time when the first embodiment is carried out.

[1-3. Functional Configuration of Information Processing Apparatus (Touch Panel and Storage Section)]

FIG. 3 is a block diagram showing a functional configuration of the information processing apparatus according to the first embodiment of the present invention. As shown in FIG. 3, the information processing apparatus 100 a includes the first touch panel 101 a, the second touch panel 101 b, a control section 110, and a storage section 120.

The first touch panel 101 a has a first contact surface which can come into contact with an operating body and is capable of acquiring first contact coordinate information indicating a contact position on the first contact surface with the operating body. Further, the first touch panel 101 a has the first display surface 102 a and is capable of displaying information in the first display surface 102 a. It can be assumed that the operating body is, for example, the finger of a user or a pen which operates the information processing apparatus 100 a.

The second touch panel 101 b has a second contact surface which can come into contact with the operating body and is capable of acquiring second contact coordinate information indicating a contact position on the second contact surface with the operating body. Further, the second touch panel 101 b has the second display surface 102 b and is capable of displaying information in the second display surface 102 b.

The storage section 120 includes, for example, the non-volatile memory 106 and stores object data and object coordinate information. The object data specifies the object 103 and includes, for example, parameters which specify properties of the object 103, such as shape, size, and color of the object 103. In the example shown in FIG. 1, the shape of the object 103 is square. Accordingly, there may be exemplified, as the object data specifying the object 103, parameters of width 10 and height 10.

The object coordinate information (may be simply referred to as “coordinate information”) indicates the position of the object 103 on the display surface 102. The object coordinate information includes, for example, a combination of display surface-identification information for identifying the first display surface 102 a or the second display surface 102 b and coordinate information within each of the display surfaces 102. The coordinate information is not particularly limited, and may be any as long as it can uniquely specify the position within each of the display surfaces 102. The object coordinate information indicating the position (x, y)=(20, 30) of the first display surface 102 a can be expressed, for example, in the form of (display surface-identification information, x, y)=(1, 20, 30). Further, for example, as long as the xy coordinates can be uniquely specified on the display surface including the first display surface 102 a and the second display surface 102 b, the display surface-identification information is not necessarily included in the object coordinate information.

[1-4. Configuration Example of Object Management Information]

FIG. 4 is a diagram showing a configuration example of object management information stored in a storage section. As shown in FIG. 4, the object management information includes, for example, the object identification information for identifying object data, the above-mentioned coordinate information, width, height, type, and the like. For the type, a value such as “entity” or “duplicate” can be set: “entity” means that it is decided that the object is present at the displayed position; and “duplicate” means that it is not decided that the object is moved to the displayed position.

[1-5. Functional Configuration of Information Processing Apparatus (Control Section)]

FIG. 5 is a diagram showing a state before an object is moved from one touch panel to the other touch panel. FIG. 6 is a diagram showing a state where the object is being moved from one touch panel to the other touch panel. FIG. 7 is a diagram showing a state after the object is moved from one touch panel to the other touch panel.

The control section 110 includes, for example, the RAM 107 and the CPU 108 and causes the object specified by the object data, which is stored in the storage section 120, to be displayed as the object 103 b (first object) at a position indicated by the object coordinate information stored in the storage section 120. When the first touch panel 101 a acquires the first contact coordinate information, the control section 110 determines whether the object 103 b is selected by an operating body 210 based on the first contact coordinate information and the object coordinate information stored in the storage section 120. For example, the control section 110 determines that the object 103 b is selected by the operating body 210 when there is overlapping coordinate information between the first contact coordinate information and the object coordinate information stored in the storage section 120.

When it is determined that the object 103 b is selected by the operating body 210, the control section 110 causes an object 103 b′ (second object), which is obtained by duplicating a part or all of the object 103 b, to be displayed at a predetermined position on the second display surface 102 b, and when the second touch panel 101 b acquires the second contact coordinate information, the control section 110 determines whether the object 103 b′ is selected by the operating body 210 based on the second contact coordinate information and in-second display surface destination coordinate information which indicates the predetermined position. For example, the control section 110 determines that the object 103 b′ is selected by the operating body 210 when there is overlapping coordinate information between the second contact coordinate information and the predetermined position.

In the example shown in FIG. 6, the control section 110 calculates the position which is the nearest to the object 103 b on the second display surface 102 b, uses the calculated position as the predetermined position on the second display surface 102 b, and causes the object 103 b′ to be displayed at the predetermined position. However, the predetermined position on the second display surface 102 b may also be a position which is fixedly decided on the second display surface 102 b. The position which is fixedly decided may be the center or the edge of the second display surface 102 b, and is not particularly limited.

If it is determined that the object 103 b′ is selected by the operating body 210, the control section 110 hides the object 103 b displayed at the position indicated by the object coordinate information and also updates the object coordinate information with the in-second display surface destination coordinate information. In the example shown in FIG. 7, the object 103 b is hidden.

When the operating body 210 performs drag operation of the object 103 b on the first display surface 102 a, the control section 110 acquires movement information indicating a direction and a distance in which the operating body 210 moves on the first contact surface while being in contact therewith. The control section 110 decides in-first display surface destination coordinate information (coordinate information which indicates the position of the object 103 b shown in FIG. 6), which is a destination of the object 103 b within the first display surface 102 a, based on the acquired movement information. For example, the control section 110 moves the object 103 b in the same direction as that indicated by the movement information and the same distance as that indicated by the movement information.

There are various methods for determining that the object 103 b′ is selected by the operating body 210. For example, there are a method of setting a candidate region 105 a from which the object is dragged to another screen as a predetermined region on the first display surface 102 a (see FIG. 6) and a method of not setting the candidate region 105 a from which the object is dragged to another screen.

First, the case of setting the candidate region 105 a from which the object is dragged to another screen will be described. In the example shown in FIG. 6, the shape of the candidate region 105 a from which the object is dragged to another screen is rectangular, but is not particularly limited and may be of any shape. Further, in the example shown in FIG. 6, the candidate region 105 a from which the object is dragged to another screen is present at a position which is near to the second display surface 102 b in the region within the first display surface 102 a, but may be present at any position. The control section 110 updates the object coordinate information stored in the storage section 120 with the in-first display surface destination coordinate information and also moves the object 103 b to a position indicated by the object coordinate information after being updated. The control section 110 determines, based on the object coordinate information after being updated and coordinate information within the candidate region 105 a from which the object is dragged to another screen, whether the object 103 b has entered the candidate region 105 a from which the object is dragged to another screen.

There are also various methods for determining whether the object 103 b has entered the candidate region 105 a from which the object is dragged to another screen. For example, the storage section 120 may store coordinate information of a predetermined point which forms the object as object coordinate information. In that case, the control section 110 determines whether the coordinate information of the predetermined point corresponds to one of a plurality of pieces of coordinate information within the candidate region 105 a from which the object is dragged to another screen, and, if the coordinate information of the predetermined point corresponds thereto, determines that the object 103 has entered the candidate region 105 a from which the object is dragged to another screen. The predetermined point may be any point as long as it is the point which forms the object, and may be, for example, the center of the object or, in the case where the object is a polygon, one of the vertices which form the polygon.

Further, for example, the storage section 120 may store coordinate information of a predetermined point which forms the object and may also store information on shape and size of the object as the object data. In that case, the control section 110 calculates a ratio of an area of a region which forms the object 103 b and corresponds to one of a plurality of pieces of coordinate information within the candidate region 105 a from which the object is dragged to another screen to an entire area of the object 103 b, based on the coordinate information of the predetermined point and the information on the shape and the size of the object. The control section 110 determines whether the calculated ratio exceeds a predetermined value, and, if it is determined that the ratio exceeds the predetermined value, determines that the object 103 b has entered the candidate region 105 a from which the object is dragged to another screen. The predetermined value used herein may be stored in, for example, the storage section 120.

Subsequently, the case of not setting the candidate region 105 a from which the object is dragged to another screen will be described. Also in this case, the storage section 120 stores coordinate information of a predetermined point which forms the object and also store information on shape and size of the object as the object data. The control section 110 calculates a ratio of an area of a region which forms the object 103 b and is not displayed in the first display surface 102 a to an entire area of the object 103 b, based on the coordinate information of the predetermined point and the information on the shape and the size of the object. The control section 110 determines whether the calculated ratio exceeds a predetermined value, and, if it is determined that the ratio exceeds the predetermined value, determines that the object 103 b is selected by the operating body 210.

The description of the methods for determining that the object 103 b′ is selected by the operating body 210 is finished. If it is determined that the object 103 b has entered the predetermined region, the control section 110 determines that the object 103 b is selected by the operating body 210 and causes the object 103 b′ to be displayed at the predetermined position on the second display surface 102 b.

[1-6. Functional Configuration of Information Processing Apparatus (Control Section: Leaving Object to Both Display Surfaces)]

FIG. 8 is a diagram showing a state where the object is left on both touch panels. When the second touch panel 101 b acquires the second contact coordinate information and also the first touch panel 101 a acquires the first contact coordinate information, the control section 110 determines whether the object 103 b′ is selected by the operating body 210 based on the second contact coordinate information and in-second display surface destination coordinate information which indicates the predetermined position on the second display surface 102 b. At the same time, the control section 110 determines whether the object 103 b is selected by the operating body 220 based on the first contact coordinate information and the object coordinate information stored in the storage section 120.

If it is determined that the object 103 b and the object 103 b′ are selected, the control section 110 omits processing to hide the object 103 b displayed at a position indicated by the object coordinate information stored in the storage section 120. Then, the control section 110 registers the in-second display surface destination coordinate information as new object coordinate information other than the object coordinate information stored in the storage section 120 without updating the object coordinate information stored in the storage section 120. That is, the coordinate information of the object 103 b and the coordinate information of the object 103 b′ are stored in the storage section 120.

[1-7. Functional Configuration of Information Processing Apparatus (Control Section: Returning Object to First Display Surface)]

It is also possible for a user to perform consciously operations of hiding the object 103 b′ displayed in the second display surface 102 b and leaving the object 103 b displayed in the first display surface 102 a to the first display surface 102 a. In this case, when the first touch panel 101 a acquires the first contact coordinate information in a state in which the object 103 b′ is displayed at the predetermined position in the second display surface 102 b, the control section 110 determines whether the object 103 b is selected by the operating body 210 based on the first contact coordinate information and the object coordinate information stored in the storage section 120. If it is determined that the object 103 b is selected, the control section 110 omits processing to hide the object displayed at a position indicated by the object coordinate information stored in the storage section 120. Then, the control section 110 hides the object 103 b′ displayed at the predetermined position on the second display surface 102 b without updating the object coordinate information stored in the storage section 120.

[1-8. Functional Configuration of Information Processing Apparatus (Control Section: Moving Duplicate Object)]

FIG. 9 is a diagram showing a state where a second object (duplicate object) is being moved in conjunction with a first object (entity object). The control section 110 acquires movement information indicating a direction and a distance in which the operating body 210 moves on the first contact surface while being in contact therewith in a state in which the object 103 b′ is displayed at the predetermined position on the second display surface 102 b. The control section 110 causes the object 103 b′ to move within the second display surface 102 b based on the movement information. For example, the control section 110 can cause the object 103 b′ to move within the second display surface 102 b in the same direction as that indicated by the movement information and the same distance as that indicated by the movement information. Thus, the second object (duplicate object) can be moved in conjunction with the first object (entity object).

Further, as shown in FIG. 9, in order that the user can easily understand the place where the candidate region 105 a from which the object is dragged to another screen exists, the region may be explicitly displayed on the second display surface 102 b.

[1-9. Functional Configuration of Information Processing Apparatus (Control Section: Deleting Duplicate Object after Elapse of Time)]

The control section 110 may determine whether the object 103 b′ is selected by the operating body 210 within a predetermined time from a start of a display of the object 103 b′ at the predetermined position on the second display surface 102 b. In that case, if it is determined that the object 103 b′ is not selected by the operating body 210 for the predetermined time, the control section 110 hides the object 103 b′ displayed at the predetermined position on the second display surface 102 b. For doing so, the control section 110 may have a function to measure the time from the start of the display of the object 103 b′ and may have a function to cause, in the case where the predetermined time elapses, an event to delete the object 103 b′ to occur. The predetermined time is not particularly limited. Further, a value of the predetermined time can be stored in the storage section 120. In addition, also in the case where it is detected that the object 103 b is moved in a shaking manner by the operating body 210, the control section 110 may cause the event to occur in the same manner as in the case where the predetermined time elapses.

[1-10. Functional Configuration of Information Processing Apparatus (Control Section: Display Method of Duplicate Object)]

The control section 110 may cause the object 103 b′ to be displayed at the predetermined position on the second display surface 102 b at a luminance lower than a luminance of the object 103 b displayed at the position indicated by the object coordinate information stored in the storage section 120. Further, the control section 110 may also cause the object 103 b′ to be displayed at the predetermined position on the second display surface 102 b in a translucent manner, or may also cause the object 103 b′ to be displayed at the predetermined position on the second display surface 102 b in a blinking manner.

[1-11. Operation of Information Processing Apparatus (Control Section)]

FIG. 10 is a flow chart showing an operation of the information processing apparatus according to the first embodiment of the present invention. As shown in FIG. 10, the control section 110 accepts an input of coordinate information indicating the coordinates on the screen via the touch panel 101 (step S101). Subsequently, the control section 110 determines whether the object is selected based on the coordinate information and object management information (step S102).

The control section 110 determines whether the object is selected (step S103). If the control section 110 determines that the object is not selected (“No” at step S103), the control section 110 proceeds to step S108. If the control section 110 determines that the object is selected (“Yes” at step S103), the control section 110 determines whether it is the entity object that has been selected (step S104).

If the control section 110 determines that it is not the entity object that has been selected (i.e., duplicate object) (“No” at step S104), the control section 110 changes duplicate object information which corresponds to the selected duplicate object to entity object information (step S105) and proceeds to step S108. The duplicate object information is, for example, the object management information in which “duplicate” is set for “type” shown in FIG. 4, and the entity object information is, for example, the object management information in which “entity” is set for “type” shown in FIG. 4.

If the control section 110 determines that it is the entity object that has been selected (“Yes” at step S104), the control section 110 registers the information of the duplicate object, which is obtained by duplicating the selected entity object, as duplicate object information in the object management information (step S106). Then, the control section 110 causes the duplicate object to be displayed in another touch panel 101 (step S107), and proceeds to step S108.

The control section 110 determines whether the event to delete the duplicate object has occurred (step S108). If the control section 110 determines that the event to delete the duplicate object has not occurred (“No” at step S108), the control section 110 returns to step S101 to continue the processing. If the control section 110 determines that the event to delete the duplicate object has occurred (“Yes” at step S108), the control section 110 hides the duplicate object displayed on the other touch panel 101 (step S109). Then, the control section 110 deletes the duplicate object information corresponding to the duplicate object to be deleted (step S110), and returns to step S101 to continue the processing.

The control section 110 causes a object 103 a′, which is further obtained by duplicating a part or all of the object 103 a, to be displayed at a predetermined position on the third display surface 102 c if it is determined that the object 103 a is selected by the operating body 210.

The control section 110 further hides the object 103 a′ displayed at the predetermined position on the third display surface 102 c if it is determined that the object 103 a′ displayed at the predetermined position on the second display surface 102 b is selected by the operating body 210.

The control section 110 may determine that the object 103 a′ displayed at the predetermined position on the third display surface 102 c is selected by the operating body 210. In that case, the object 103 a displayed at the position indicated by the object coordinate information stored in the storage section 120 and the object 103 a′ displayed at the predetermined position on the second display surface 102 b are hidden. The control section 110 hides the object 103 a′ displayed at the predetermined position on the second display surface 102 b and also updates the object coordinate information stored in the storage section 120 with in-third display surface destination coordinate information, which indicates a predetermined position on the third display surface 102 c.

With reference to FIG. 13 (refer to other figures as appropriate), a description will be made on a method of moving the object to another screen in the case where the same candidate region from which the object is dragged to other screens is used for other destination panels. The control section 110 acquires movement information indicating a direction and a distance in which the operating body 210 moves on the first contact surface while being in contact therewith. The control section 110 decides in-first display surface destination coordinate information, which is a destination of the object 103 a within the first display surface 102 a, based on the acquired movement information, and updates the object coordinate information stored in the storage section 120 with the in-first display surface destination coordinate information. The control section 110 updates the object coordinate information and also moves the object 103 a to the position indicated by the object coordinate information after being updated.

The control section 110 determines, based on the object coordinate information after being updated and coordinate information within the candidate region 105 a from which the object is dragged to other screens on the first display surface 102 a, whether the object 103 a has entered the candidate region 105 a from which the object is dragged to other screens. The control section 110 may determine that the object 103 a has entered the candidate region 105 a from which the object is dragged to other screens. In that case, the control section 110 determines that the object 103 a is selected by the operating body 210, and causes the object 103 a′ to be displayed at the predetermined position on the second display surface 102 b and also causes the object 103 a′ to be displayed at the predetermined position on the third display surface 102 c.

With reference to FIG. 14 (refer to other figures as appropriate), a description will be made on a method of moving the object to another screen in the case where candidate regions from which the object is dragged to other screens are present for respective destination panels. In the same manner as in the case of moving the object in the case where the same candidate region from which the object is dragged to other screens is used for other destination panels, the control section 110 updates the object coordinate information stored in the storage section 120 with the in-first display surface destination coordinate information and moves the object 103 a to the position indicated by the object coordinate information after being updated.

The control section 110 determines, based on the object coordinate information after being updated, coordinate information within the candidate region 105 b from which the object is dragged to another screen on the first display surface 102 a, and coordinate information within the candidate region 105 c from which the object is dragged to another screen on the first display surface 102 a, whether the object 103 a has entered the candidate region 105 b from which the object is dragged to another screen or the candidate region 105 c from which the object is dragged to another screen. If it is determined that the object 103 a has entered the candidate region 105 b from which the object is dragged to another screen, the control section 110 determines that the object 103 a is selected by the operating body 210 and causes the object 103 a′ to be displayed at the predetermined position on the second display surface 102 b. If it is determined that the object 103 a has entered the candidate region 105 c from which the object is dragged to another screen, the control section 110 determines that the object 103 a is selected by the operating body 210 and causes the object 103 a′ to be displayed at the predetermined position on the third display surface 102 c.
